Initial System Setup
To begin setting up your Marantz Cinema 70s, connect the unit to your television using the HDMI Monitor Out port, ideally utilizing the eARC or ARC port on your display for enhanced audio return. Connect your speakers to the terminals on the rear panel, ensuring that the positive and negative wires match the corresponding red and black terminals. Once the physical connections are made, power on the receiver and follow the on screen Setup Assistant. This graphical interface will guide you through connecting to your Wi-Fi network and performing Audyssey MultEQ room calibration. Use the included cardboard microphone stand and calibration microphone to measure your room's acoustics, which allows the receiver to automatically optimize the sound levels and equalization for your specific listening environment.
Daily Operation and Features
Operating the Cinema 70s is designed to be intuitive via the front panel controls, the included remote, or the Marantz AVR Remote app. The front porthole display provides essential information such as the current input and volume level. You can switch between sources like gaming consoles, media players, or the built in HEOS streaming platform using the input selector. For music, the HEOS app allows you to stream high resolution audio directly from services like Tidal, Pandora, and Amazon Music HD to multiple rooms. If you prefer a more focused listening experience, engaging the Pure Direct mode will shut down unnecessary internal circuitry to provide the cleanest possible signal path for your audio.
Advanced Customisation
You can further tailor the audio performance by accessing the web manual or the deeper settings menu to adjust crossover frequencies for your speakers and subwoofers. For those using the receiver in a multi room configuration, the Zone 2 output can be configured to play a different audio source in another part of your home simultaneously. The receiver also supports 8K video pass through and gaming features like Variable Refresh Rate and Auto Low Latency Mode, which can be enabled in the HDMI setup menu to ensure peak performance for modern consoles. If you use voice assistants, you can integrate the receiver with Alexa, Google Assistant, or Siri for hands free control of volume and playback.
Troubleshooting and Maintenance
If you encounter issues with audio output, first check that the speaker wires are securely fastened and that no stray strands are touching the chassis or other terminals. If the receiver does not appear on your network, try power cycling your router and then restarting the unit by holding the power button for several seconds. For video issues, ensure you are using high speed HDMI cables rated for 8K or 4K/120Hz if you are using high performance sources. If the system becomes unresponsive or you experience persistent software glitches, you can perform a firmware update via the settings menu to ensure you have the latest stability improvements. In cases where the unit enters protection mode, indicated by a blinking red light, disconnect the power and check for short circuits in your speaker wiring before restarting.
